Where the heil is your sense of your humor?

That was the reaction of a Hong Kong judge who ruled that Jefferies Group wrongfully dismissed its former Asia head of equity trading for including a link to a popular Hitler parody video in a widely distributed newsletter to clients.

Judge Conrad Seagroatt said the investment bank was being “hypersensitive” and “irrational” in 2010 when it fired Grant Williams for drawing attention to the satirical video, which mocked JPMorgan Chase boss Jamie Dimon as well as commodities head Blythe Masters.

Williams embedded a link to a clip from the 2004 German movie biopic “Downfall,” which has become a popular Internet meme.

There have been hundreds of homemade spoofs on YouTube touching on everything from sports to the stock market. Most have been created by dubbing over the audio or creating subtitles during a climactic scene in which an enraged Hitler loses it in front of his subordinates.

The link in Williams’ newsletter relates to an off-color version of the video with Hitler serving as a stand-in for Dimon, blasting his closest lieutenants over a silver trade gone wrong.

“Do you realize I had to a– f–k Bernanke to get this deal?” he rages.

Seagroatt, a justice for Hong Kong’s High Court, said he would deliver his written reasons for ruling in the case at a later time. Williams is seeking $13 million in damages.

A spokesman for Jefferies declined to comment on the ruling.

“Jefferies was seen as a company associated with that video that insulted in a quite humiliating way a competitor and business partner,” a lawyer for Jefferies told Bloomberg News, which reported the decision.
